I used my Atomstack R1 chuck rotary on my Atzer P20 Pro. After unplugging the chuck, I lowered my rig back to normal.
Now, all my settings are messed up. I made sure to unclick “enable rotary.” My laser home is in a completely different area. It tries to go beyond the rig’s limits and makes a horrible noise. When I try to go to Y=0 X=0 it goes to the wrong spot.
Any help would be great. If screen shots would be helpful, please let me know what you would like to see.
Please post a screenshot of your entire Lightburn screen with your project loaded and the Cuts/Layers Panel and Laser Panel visible. Also post a screenshot of the Settings Window (Gears icon) with the Units and Grids tab visible and post a screenshot of the Device Settings Window (Wrench and Screwdriver icon). Also, enter $$ in the console window and copy/paste all the output here.

Did you restart the laser after removing the rotary?
What, if any settings did you change to use the rotary?
Do yourself a favor and turn off beginner mode. It opens up several settings that you currently cannot control.
I didn’t restart after turning off the rotary, but I did after I realized there was something wrong.
These are the setting I had for the rotary.
So you have restarted the laser since removing the rotary. Did you make any changes to GRBL settings when you installed the rotary?
When it starts, what corner does it go to?
Yes, I didn’t change anything else (that I know of, I’m still new to Lightburn).
The laser homes to the lower right hand corner and act like it is trying the move past the end of the machine.
I had it homing to the lower left hand side.
This machine has limit switches, correct?
If so, enter this into console one at a time, pressing enter after each one then restart the laser.
$3=2
$23=2
Report your findings.
If it doesn’t have limit switches we will do something different.
I don’t think it has limit switch. I entered the values you said and nothing happened
It still tries to home off the rig and to the lower right corner

That doesn’t make any sense. Something should have happened, even if no change in behavior.
You have auto home on startup enabled, so every time you connect to Lightburn it should try to home. If the machine doesn’t have limit switches you have to manually home it and would need that setting disabled.
Enter $$ again and verify that the changes took. If they did, click the home button and let me know which direction it goes.

Dumb question, Is there an easy way to tell if I have limit switches or not?
OMG! I’m a moron! I didn’t remove the harness for the rotary. I just plugged it into the control. 
Once I removed the harness it works fine now.
Thank you for all your help. Sorry, I’m an idiot.
Glad it works.
In the console type $3=3 and $23=3 followed by enter after each one. This should restore any changes we just made.
Thanks again
So you unplugged the adapter harness from the rotary end and plugged that back into the motor rather than unplugging the adapter harness from the machine end?
That makes perfect sense as often the adapter harness reverses the motor direction.
